I am installing composer with the following cammand
curl -s https://getcomposer.org/installer | php
But I am keep getting below error message
Zafars-MacBook-Pro:etc zafarsaleem$ curl -s https://getcomposer.org/installer | php
#!/usr/bin/env php
Some settings on your machine make Composer unable to work properly.
Make sure that you fix the issues listed below and run this script again:
The detect_unicode setting must be disabled.
Add the following to the end of your `php.ini`:
detect_unicode = Off
A php.ini file does not exist. You will have to create one.
How can I install composer be removing above error?
EDIT
Zafars-MacBook-Pro:etc zafarsaleem$ php --ini
Configuration File (php.ini) Path: /etc
Loaded Configuration File: (none)
Scan for additional .ini files in: (none)
Additional .ini files parsed: (none)
Latest Edit
After some research I found that php.ini file which is being used is in /etc/php.ini. However, when I checked this file in /etc folder it wasn't there. /etc folder contained php.ini.default folder which linked to /private/etc/php.ini.default. So I added detect_unicode = Off in /etc/php.ini.default and the renamed this file to php.ini. Now when I execute below command
curl -s https://getcomposer.org/installer | php
OR
sudo curl -s https://getcomposer.org/installer | php
Then I get following errors
Zafars-MacBook-Pro:/ zafarsaleem$ sudo curl -s https://getcomposer.org/installer | php
#!/usr/bin/env php
All settings correct for using Composer
